Today I did some wiring upgrades to my trailer in the form of replacing scotch connectors with heat-shrunk, soldered connections. I also determined placement under my truck for a yet-to-be-made shelf that will hold my OBA project's air tank(s), and I sketched out rough plans for said shelf so that I can make a wood prototype of it next weekend. The idea behind this is that I'll test the plan with wood, tweak as necessary, and, once happy with it, I'll commission a local welding company fabricate a steel version to match.
